A randomized controlled study comparing remote robotic pancreaticoduodenectomy with local robotic pancreaticoduodenectomy

INTERVENTION: Intervention Group (Remote Surgery Group):Toumai Thoracoabdominal Endoscopic Surgical System Remote Surgery;Control Group (Local Surgery Group):Toumai Thoracoabdominal Endoscopic Surgical System Local Surgery; CONDITION: Tumors around the pancreas and ampulla PRIMARY OUTCOME: Surgical success rate (technical);Surgical success rate (safety); SECONDARY OUTCOME: Incidence of surgical complications;Intraoperative blood loss;Robot‐assisted surgery time;Number of days of hospital stay after surgery;Device performance indicators: incidence of severe system failures, assessment of the device’s performance in use, etc.;During the surgery, the network signal latency, total latency, and packet loss rate are recorded.;Safety assessment indicators: overall incidence of complications, incidence of device defects, etc.; INCLUSION CRITERIA: 1.18 years <= actual age <= 80 years; 2.Patients who require laparoscopic surgery and have surgical indications for pancreaticoduodenectomy; 3.Physically fit to undergo abdominal surgery; 4.Willing to cooperate and complete study follow‐up and related examinations; 5.Subjects or their legal representatives voluntarily participate in this trial and sign the written informed consent form.
